Daikin Solar tank with integrated interior heat pump unit
008.1420744 – 06/2015
Installation and maintenance manual
45
Hot water does not warm
up
DIP switch configured incorrectly
● Check DIP switch setting on board A1P
(see section 7.4).
Hot water supply switched off (e.g. switching
time program is in the economy phase,
parameters for hot water supply have been
set incorrectly).
● C
heck the operating mode setting.
● Check the request parameters.
Storage tank charging temperature too low. ● Increase the target hot water temperature.
Draw-off rate too high. ● Reduce the draw-off rate, limit throughput.
Output of heat pump too low.
● Check the switching times for room heating and hot
water supply for overlaps.
Water quantity in heating system too low.
● Check the primary pressure in the expansion
container and the water pressure, if necessary, refill
the heating water and reset the primary pressure
(see chapter 6.5).
Optional backup heater (EKBUxx) or alterna-
tive heater not switched on.
● C
heck the mains supply to the backup heater
(EKBUxx).
● T
hermal protection switch (STB) on Backup Heater
(EKBUxx) has been triggered. Unlock.
● C
heck the parameters [Function Heating Rod] and
[BUH s1 power] and [BUH s2 power].
Room cooler does
not cool
Water flow too low.
● Check that all stop valves of the water circuit are
completely open.
● C
heck that the water filter is dirty.
● Check that the expansion tank is defective.
● Fully
vent the heating system and device-internal
circulation pump.
● On the control unit (rotary switch position "Info" )
check that there is sufficient water pressure (>0.5 bar),
i
f necessary, refill the heating water.
● Check that the resistance in the water circuit is not too
high for the pump (see installation manual for
"
Technical Data").
"Cooling" switched off (e.g. room thermostat
requ
ires "Cooling", but switching time pro-
gram is in economy phase, outside tempera-
ture too high).
● Check the operating mode setting.
● C
heck the request parameters.
● Check setting of the date, time and switching time
program on the control unit.
Refrigerant compressor is not working.
● If
there is a backup heater installed (EKBUxx):
Check whether the return flow temperature backup
heater heats up to at least 15 °C (if the return flow
temperature is low, the heat pump first uses the
backup heater in order to reach this minimum return
flow temperature).
● C
heck the mains supply to the backup heater
(EKBUxx).
● Thermal protection switch (STB) on Backup Heater
(EKBUxx) has been triggered. Unlock.
System is in the operating mode "Heating". ● Swi
tch the operating mode to "Cooling".
Outdoor temperature < 4 °C
The heat pump has automatically switched to the "Heating"
operating mode so as to be able to guarantee frost protec-
tion should the external temperature drop further. Room
cooling not possible.
